The
High Dynamic Range/HDR feature that enhances the 2160p image has been
joined by 12-color bit Dolby Vision starting with the original
Despicable
Me
in 4K and the HDR group is about to introduce HDR10+ in early 2019,
expanding its 10-color bit capacity in 2019. So far, regular
Blu-rays have been included with the 4K versions in the following
releases so far, save two, plus a few titles have had no HDR at all,
but that too is rare...
